Primer empleo de jóvenes técnicos: Oportunidades diferenciales según clase social de origen
No full textLa educación técnico profesional (ETP) ha sido objeto de debates respecto a las oportunidades que brinda en materia laboral y educativa. Esta modalidad, que había sido profundamente atacada en el periodo neoliberal en Argentina, ha vuelto a cobrar importancia para el desarrollo económico-productivo y la movilidad social intergeneracional, aunque en un contexto diferente al de su apogeo en el siglo anterior. En este marco, examinamos de qué manera la clase social de origen condiciona las características del primer empleo de egresados de ETP en Argentina, indagando esta influencia a lo largo del periodo post egreso secundario. Para abordar nuestro problema se analizan datos estadísticos secundarios del Instituto Nacional de Educación Tecnológica (INET). Consiste en un panel que durante 8 años (2009, 2011, 2013, 2017) encuestó a una muestra probabilística nacional de 1500 ex-estudiantes de ETP. Los resultados muestran que las clases alta y medias tienden a insertarse de manera más tardía y en trabajos de mejor calidad respecto a las clases populares y que estas desigualdades se refuerzan en la medida en que el primer empleo sucede de manera temprana. A su vez, cuando las inserciones son tardías, encontramos quiebres en las oportunidades de las fracciones de las clases populares.Fil: Lemos, Sebastian.

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
Higher education, job placement and social class of origin: Accumulation of (dis)advantages of young technicians in Argentina
Full text linkEl presente artículo analiza el proceso de acumulación de desventajas que opera entre la clase social de origen, la inserción laboral y las trayectorias educativas de egresados de escuelas técnicas en la Argentina. En primera instancia, en el plano laboral, se abordan las desigualdades de clase en el tipo de primer empleo obtenido y su variación a medida que dicho evento se adelanta o atrasa en la vida de los jóvenes técnicos y, en segunda instancia, se observa el efecto de las desigualdades de clase, el tipo de empleo y las elecciones de carrera en el abandono, permanencia o graduación del nivel superior.Los datos del artículo son secundarios y provienen de un estudio de panel que durante 8 años (2009, 2011, 2013 y 2017) encuestó a una muestra probabilística de estudiantes y luego egresados de escuelas técnicas estatales de la Argentina. Se utilizan técnicas estadísticas descriptivas e inferenciales: gráficos trivariados, regresiones logísticas multinomiales y la lectura de promedios de efectos marginales.Los resultados develan un proceso donde las desigualdades de clase, laborales y educativas se solapan. Específicamente, los jóvenes de clases populares tienden a obtener peores inserciones laborales y menos chances de obtener credenciales educativas superiores, más aún cuando ingresan tempranamente al mercado de trabajo. Sin embargo, a medida que las inserciones se retrasan, los empleos técnicos y formales ganan presencia para estas clases, y a su vez, el optar por carreras terciarias funciona como un mecanismo que equilibra las desigualdades de clase y el impacto del primer empleo en las trayectorias educativas superiores.This article focuses on the process of accumulation of disadvantages that operates between the social class, labour placement and the educational trajectories of graduates of technical schools in Argentina. In the first instance, at the labour level, class inequalities are addressed in the type of first job obtained and its variation as said event advances or delays in the life of young technicians and, secondly, the effect of class inequalities, type of employment, and career choices on dropout, retention, or graduation from higher education. The data in the article is secondary and come from a panel study that for 8 years (2009, 2011, 2013 and 2017) surveyed a probabilistic sample of students and later graduates of state technical schools in Argentina. Descriptive and inferential statistical techniques are used: trivariate graphs, multinomial logistic regressions, and the reading of averages of marginal effects. The results reveal a process in which class, labour and educational inequalities overlap. Specifically, youth from the lower classes tend to have worse job placement and fewer chances of obtaining higher educational credentials, even more so when they enter the job market early. However, as insertions are delayed, technical and formal jobs gain presence for these classes, and at the same time, opting for tertiary careers works as a mechanism that balances class inequalities and the impact of the first job on trajectories higher education.Fil: Lemos, Sebastian.

koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
